Tory MP Bob Blackman has said that far from introducing gay marriage, David Cameron should bring back the Section 28 law that banned teachers from talking about homosexuality.

On Friday afternoon the Harrow East told BBC News that the principle of same-sex marriage was "wrong in the first place".

”A very small number of people have same-sex relationships where children are involved," Pink News reports him as saying. "There may be some."

"The key point is what is happening in schools particularly to very young children, what they’re educated and what they’re told.

“I was one of those that strongly believed that Section 28 was the right rules to have in school so that we should not promote in any way shape or form promote same-sex relationships, I still abide by that and feel thats the right way forward, and if teachers are forced to say same-sex relationships are equivalent to heterosexual relationships I’d be very opposed to that.”

Introduced in 1989 by the then Conservative government, Section 28 made it unlawful for local authorities to ‘promote homosexuality’.

In practise it meant councils could not fund books, leaflets or any other material that presented gay relationships as notmal and its introduction prompted protests and was the trigger for the creation of gay rights group Stonewall.

The law was repealed by the Labour government in 2000.

Tony McNulty, the former Labour MP who lost his seat to Blackman at the 2010 election, branded the comments "disgraceful".

"So sorry my failure let this abominable fool, Blackman, become an MP. Lets make him a one-term wonder," he said.

He added: "I was the MP for Harrow East - and lost the election to this fool."
